The Chemistry of Natural Products: 6
The Chemistry of Natural Products: 6 discusses some of the advances in the chemistry of sesquiterpenic lactones. This book presents the studies on terpenoids isolated from Compositae. Organized into 10 chapters, this book begins with an overview of the revised structures of some guaianolides and germacranolides. This text then examines the advances in the field of steroidal alkaloids and sapogenins possessing the C27-carbon skeleton of cholestane. Other chapters consider the usefulness of steroidal glycosides of digitalis as life-saving products. This book discusses as well the microbiological oxidation of the five-membered ether sesquiterpenes guaioxide and liguroxide using Mucor parasiticus. The final chapter deals with the application of hypofluorites, particularly trifluoromethyl hypofluorite, in the synthesis of fluorinated steroids. This book is a valuable resource for organic chemists, phytochemists, plant biochemists, botanists, and other scientists. Students and research workers who are interested in the chemistry of natural products will also find this book extremely useful.
Annual Reports on NMR Spectroscopy
Over recent years, no other technique has grown to such importance as that of NMR spectroscopy. It is used in all branches of science where precise structural determination is required and where the nature of interactions and reactions in solution is being studied. Annual Reports on NMR Spectroscopy has established itself as a means for the specialist and non-specialist alike to become familiar with new applications of the technique in all branches of chemistry, including biochemistry, and pharmaceutics. This volume focuses on theoretical aspects of NMR nuclear shielding and on applications of NMR to polymer science.
Diterpenes of Flowering Plants
More than 1200 diterpenes have been identified from approximately 550 Compo sitae taxa (Figure 1 [pp. 219-384], Tables 1-3 [pp. 7-218]). The annual output of such reports rose sharply during the past several years, a trend that was also reflected by other major lipophilic constituents of the Compositae: acetylenes (63, 465), sesquiterpene lactones (266, 458), and benzofurans and chromenes (429). Unlike these other natural products, no review of the diterpene chemistry of the Compositae has been published. Given the bulk of data currently on hand, a review of this topic is clearly overdue. Several major goals influenced the preparation of this review. The first was to provide a useful referen...
Pharmacognosy and Phytochemistry
In znodern pharznacognosy chemical and physical-cheznical methods are being used znore and more for the investigation of medicinal plants. This important fact and the increasing involvement of chemistry, biocheznistry and botany in pllarmaceuti cal, znedicinal and general biological questions usher in a new epoch in the disco very of medicinal substances and the development of drugs derived from the plant kingdom. One of the guiding ideas of the first ""Syznposiuzn on Pharznacognosy and Phytocheznistry"" was to promote these developments, to provide an additional sti znulus and to establish.
Flavonoids of the Sunflower Family (Asteraceae)
Flavonoids are secondary plant products that have previously been shown to be helpful in determining relationships among plant groups. This work presents comprehensively the occurrence, patterns of variation, and systematic and evolutionary importance of flavonoids in the sunflower family (Asteraceae), the largest family of flowering plants (23,000 species). It gathers together the more than 2500 reports of flavonoids in Asteraceae published between 1950 to the present and interprets these data in context of new taxonomic (especially generic) alignments. The authors discuss flavonoid patterns with reference to modern phylogenetic studies based on morphology and DNA data. This book provides, therefore, the most exhaustive synthesis and evaluation of the systematic and evolutionary import of flavonoids ever accomplished for any large family of angiosperms.

Terpenoids: Structure, Biogenesis, and Distribution
Recent Advances in Phytochemistry, Volume 6: Terpenoids: Structure, Biogenesis, and Distribution covers the advances in the chemistry and biochemistry of terpenoids, and the use of information regarding the occurrence of such compounds in genetics and population ecology. The book discusses the applications of physical methods to some structural and stereochemical problems in terpenes and steroids; novel sesquiterpenes isolated in composites; and the chemistry and biogenesis of the quassinoids (Simaroubolides). The text then describes the recent developments in the biosynthesis of plant triterpenes; the mechanisms of indole alkaloid biosynthesis, recognition of intermediacy and sequence by short-term incubation; and the biochemistry and physiology of lower terpenoids. The genetic and biosynthetic relationships of monoterpenes; and the confirmation of a clinal pattern of chemical differentiation in Juniperus virginiana from terpenoid data obtained in successive years are also encompassed. Botanists, biochemists, and people involved in the study of phytochemistry will find the book invaluable.
